This is a cute half size breadboard, good for small projects. It's 2.2" x 3.4" (5.5 cm x 8.5 cm) with a standard double-strip in the middle and two power rails on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm) and stick it onto an Arduino protoshield. You can also cut these in half with a saw to create 2 tiny breadboards, or "snap" these breadboards together either...

This is a really nice power supply. It's a switching DC supply so its small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 9V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel jack, positive tip. This supply is designed to work anywhere in the world, 100V-240V AC wall power, you'll just need a low cost plug adapter. New! This adapter...

This is a preprogrammed Atmega328P chip, useful if you want to make your own Arduino-compatible or repair a damaged chip on an exisiting Arduino UNO, Duemilanove, Diecimila, or NG! This chip is programmed with 'ADAboot', my version of the bootloader that is "quick-start" NG/diecimila/duemilanove/UNO-compatible. This means that there is still a 5-second delay from when you press the reset button to when the Arduino runs the...

This is a 9V battery pack with on/off switch and a pre-attached 5.5mm/2.1mm barrel plug. Use this to battery-power your Arduino (or other electronic projects) - it's ready to go out of the box! Battery & screw not included.

Add a power switch to any project simply by plugging this between the power supply. This is the most useful thing you never knew you needed! You'll want to pick up a bunch for your electronic projects. Comes with a 5.5/2.1mm barrel jack on one end an a plug on the other. In between is an in-line switch that is rated for 125V and 2Amps (its normally used for lamps, we suppose). Since most people will be using it with no more than 12VDC, we think...

By popular demand! We now have the plates from the ARDX available separately. Acrylic plate is engraved and cut here at the Adafruit factory. There are mounting holes for your Arduino and a space that fits a half sized breadboard very nicely. THIS DOES NOT FIT THE ARDUINO MEGA. Comes with: 3mm thick plastic plate with engravings 2 x 4-40 3/8" machine screws for attaching your Arduino 4 x 4-40 hex nuts 4 x rubber bumpers, keeps the board...

The Arduino Esplora is a fun new game controller-shaped microcontroller board derived from the popular Arduino Leonardo. What makes the Esplora cool (and a great starter board) is that it has a number of built-in, ready-to-use sensors already on the board, for easy interaction. It's designed for people who want to get up and running with Arduino without having to learn about the electronics wiring first. For a step-by-step introduction to...

These stickers are a must for anyone making a breadboarded Arduino-compatible. They fit right on top of a DIP ATmega328 (or '168) chip, and clearly indicate every pin as it would be called in the Arduino IDE. No more looking up the datasheet or schematic! The stickers are made of a tough vinyl, usually used for bumper stickers, so they will not fade, scratch, or wrinkle. The stickers are die cut already into a rounded rectangle that fits on...

We have so many Internet-connected goodies in the shop, we figured it's time to carry a cable so you can easily connect them up! This cable is 10 feet long, black and has all 8 wires installed. Perfect for use with the BeagleBone, Arduino Uno Ethernet, Arduino Ethernet Shield, NETduino Plus, Patch Shield, PoE Injector cables, IoT Printer pack or any other Ethernet-cable-needing product! This is a 'straight-thru' cable, not a cross-over cable. If...
